Exams and Tests

The most important test that is performed is a blood sugar (glucose) determination when the patient is first symptomatic. This test will most likely be repeated several times during an emergency department visit to ensure stable levels prior to discharge.

• A history and physical examination will be performed in an attempt to determine why the insulin reaction occurred. Bring a medication list, including insulin dose, to the hospital.


• If neurologic symptoms continue, other tests that may be performed include electrolyte determinations (such as sodium and potassium), kidney function tests (BUN/creatinine), and other endocrine function tests.


• A sample of urine may be tested.


• An ECG may be performed if an associated heart attack is suspected with the insulin reaction.


• A chest x-ray may be performed if pneumonia or vomiting (during unconsciousness) is suspected.
